Self Assembly/Bone Regrowth (Episode #705Z)

KQED Kids: Wed, May 29, 2013 -- 4:00 PM

Self Assembly - Keely and Connor learn about self-assembly at the Children's Museum of Houston. The museum staff suggest they visit Rice University, where scientists use self-assembly to make things at the nanoscale. At Rice, a scientist helps the kids use self-assembly to make and "pop" microcapsules. The kids then try out a similar technique at home, encapsulating chocolate sauce, mint and other flavors in alginate beads to serve on ice cream. Bone Regrowth - Kobel, Nathan, and Adam go to the Oregon Museum of Science and Industry (OMSI), where they learn that scientists are using nanotechnology to help regenerate nerves and bones. A scientist from Brown University explains that a solution of nanotubes and minerals is injected into the fracture and forms a scaffold to encourage bone regrowth. The kids want to know why both ingredients are needed to repair the bone. They try solutions with different amounts of each ingredient on sponges and test how much weight each treated sponge can support.

Gecko Feet/Nasturtium Leaves (Episode #704Z)

KQED Kids: Wed, May 22, 2013 -- 4:00 PM

Gecko Feet - Jennifer and Nooshin like rock climbing. They wonder how some lizards can climb rocks so easily. They visit the Lawrence Hall of Science in Berkeley and compare the climbing ability of different lizards. They notice that the best climbers are geckos. They visit a lab at the University of California Berkeley to find out why, learning that special, nanoscale hairs on gecko feet are the secret to their amazing climbing abilities. Nasturtium Leaves - Jasmine and Melinda wonder why water beads up on some plants and not others. They head to San Francisco's Exploratorium, where they learn that surfaces at the nanoscale aren't always smooth, and that nano hairs on nasturtium leaves cause them to be water repellent. The girls collect other plants with hairy leaves and test their ability to repel water. They take some samples to Stanford University for up-closing imaging and compare the structure of nasturtium leaves to water-resistant fabric.

Hockey Sticks/Butterfly Wings (Episode #702Z)

KQED Kids: Wed, May 8, 2013 -- 4:00 PM

Hockey Sticks - Nicholas and Jordan love hockey. They know that carbon nanotubes are used in some hockey sticks, but aren't sure how the tiny structures change the equipment. They head to Boston's Museum of Science to learn more about carbon nanotubes. Then, they put their sticks to the test on the ice. Finally, with help from scientists at Harvard University, they compare the tensile strength of the sticks and use powerful microscopes to "see" carbon nanotubes. Butterfly Wings - Emily and Julie check out the Magic Wings Butterfly House at the Museum of Life and Science in Durham. They wonder why butterfly wings are so colorful. They learn that iridescence in some butterfly wings - like the iridescence of soap bubbles - results from their structure. At Duke University, the girls learn how to determine whether colors in wings are the result of pigment or nanoscale structures. They test butterfly wings and learn that blue iridescence is due to structure, not pigment.

They search Boston for examples of a billion. Then they visit laboratories at Harvard University to find examples of nanoscale objects on their quest to "see" a nanometer.
* Where's Nano? Regina, Linda, Harrison, Jared, Lorenz, and Randi, visit the "Zoom In" exhibit at the Morehead Planetarium and Science Center in Chapel Hill. They wonder what examples of nanoscale science and technology they can find in their everyday lives. Their nano "scavenger hunt" takes them to the University of North Carolina Chapel Hill, where a scientist helps them print images of nanoscale structures.
